What does a bug mean to Riot; a dialogue of questions.

Here's a bug. Wooglet's Witchcapp tooltip doesn't show the bonus ap earned from passive. Easy enough fix. How about the visual bug that shows Aurelion Sol's trio balls of fire floating piecewise around their axis of orbit. Kinda like they update only when asked if at that. How about the thin slivers of text that seem to float above the attack damage and ap numbers in the ui. Well, let's talk about these three bugs and the thousands more that exist because of poor quality control and poor development standards but won't be fixed because Riot just doesn't care about a quality game.

What does it take for Riot to fix a bug?

This isn't a novel question, rather it's been said since pre-alpha testing. Honestly from being around that long I know that Riot has had some ups and downs in total bugs per patch created. But really we might say that it takes a learning experience to prevent more from happening. Riot QA dept. take note.
